What is oxygen?

Lanka oxygen is a device used to melt or cut steel too thick so that conventional oxy-acetylene burner can be cut using a long steel tube or oxygen feeding under pressure to the preheated area. Oxygenic spear achieves this cutting effect by causing oxidation and melting the reaction of the preheated area of ​​the material, which will be cut by directing the oxygen current to it. The oxygen current blows this area of ​​the molten steel away and creates a cut. The thickness of steel and cast iron up to eight feet (about 240 cm) can be melted using an oxygen spear that is not possible using a conventional cutting device. Delivery of constant 40-50 PSI (2.7-3.5 bar) flow to the lance and suitable safety equipment resistant to fire. The spear pipe itself should be so long practical, as it is constantly consumed during the cutting process and should keep the operator at a safe distance from the cutting space.

The cutting process is also relatively simple with regard to the thickness of the material that melts. The edge of the steel is heated to a bright cherry red color oxy-acetylene burner and the tip of the oxygen spear is then applied to this area. The pressure flow of oxygen causes an intense oxidation reaction on the surface of the steel, which in turn causes the top of the localized temperature sufficient to melt the material. Oxygen also serves to blast this molten material and create a channel or cut in steel. This process creates an impressive spark shower at a considerable distance, so it is necessary to ensure that workers and equipment are held far from the cutting area.

If the cut material is from the Ntlouštka Opiration, after the start of the cutting process, the oxy-acetylene burner may be removed. In the case of thicker materials, the burner should be used to constantly maintain the area of ​​preheated material in front of oxygen. During the operation, the Lanka tube will be consumed by intense heat at the section of the section andIt should be discarded as soon as it is too short to be used safely.

Thanks to these properties of oxygen spear, it makes it a particularly efficient and cost-effective method of cutting steel and cast iron materials too thick to cut normal oxy-acetylene torches. However, Lanka's oxygen should not be confused with a thermal or thermal spear. This device works on a similar principle, but uses a bundle of iron and magnesium rods inside the Lanka tube to create a separate and extremely hot cutting flame.
